How many times are you planning to post this in the same day?

Maybe the alternative fuel forum will have more activity: https://www.ford-trucks.com/forums/forum146/

 

If you are trying to fill your trucks tank from a small cylinder it won't work, it has to be pumped in, in a liquid state. The residual gas flowing from your small tank will not do your big tank any good.
